Serviria la zeolita igualmente no?

In a tank like that it’s expected to grow a lot of algae and cyano because there is nothing to compete with the algae it’s plain gravel and nutrients 😂

That makes no sense Cory gave us many good advices even at expenses of profit when he teaches how to customize hang on back filters and remove the cartridges well he sells cartridges! What’s the problem not having interest in your system? He said even canisters are bad and he sells these filters lol

I'm so glad I got into this hobby AFTER I started my garden & greenhouse, otherwise all of this water & material would be such a waste. 😎 And the garden also supplies the inoculated & nutrient-rich base I need for my dirt-planted tanks.

I have had goldfish for years. I have hanging filters, I start with feeder fish, that within a year are 7-8" long and I move them successfully to an outdoor pond. I add a scope of food grade diatomaceous earth everytime I add water, I don't have sick or dying fish. I now have fancy and orandas, also with no issues. I also add DE to my fish pond. This has worked for me for over 20 years 🤷

Hi Dr. Novak, i plant on using a sump and bcb basket. Do you have a suggestion for what type of substrate I should use?

Well, I beg to differ Sir. I have a 3 year old 75g tank with 3 Central American Cichlids around 7 inches each. I have 2 HOB filters - I have my Pothos in both of these filters planted in Bio-Max and Filter floss on top to help keep my water clear. I feed my fish once a day every day. I have 0ppm Ammonia and Nitrite.... My Nitrate level stays between 5ppm-10ppm constantly. I only do water changes 2x a month. Before this setup, I had 2 canister filters and NO PLANTS... My Nitrates would range between 20ppm-120ppm and I was doing WEEKLY water changes, sometimes 2x a week. Plants will CONSUME NITRATES... they will NOT eliminate Nitrates but they will keep it at a MINIMUM!!!!

Thank you for the review. Won't be purchasing these.

I’m surprised your fish aren’t going into a feeding frenzy

I've been watching a lot of videos on this channel and I have to say, they're really interesting! I think I'm ready to try the Plenum on all of my tanks, but I'd like to start on my small 10 gallon tanks first. I have a question: how do you cut the uplift tubes to make them shorter? I've tried using a handsaw, but they always end up breaking. Any tips on what to use instead?

Deep sand bed is the reason it works not the undergravel filter The deep sand beds can be viable but it’s not for free you need to know how to maintain them You need a good sump refugium skimmer and all that jazz There is a serious issue you aren’t considering here the saltwater just can’t be high nutrient aquatic environment otherwise it’s a disaster In comparison to fresh water the saltwater concentrations of nitrites and nitrates are much much lower

When you make the bags can you mix the fluorite red and oil dry together or do you have to layer them together ✌️🙏🇨🇦

The problem I am having is different from this. The feeder doesn't spin when times are set. It does spin when I do it manually, but for some reason The timer doesn't kick in.

Because it’s bad 😂 that’s why

I have a Geophagus Balzanii in my aquarium. I have named him/her Geo and it is doing well.

I believe it’s 11 gallons

I thought you recommended squirting a little iron in every day. Is that only for tanks with CO2?

I think, the idea here is why it's expensive is because of the brain, the electronics. You can change the pump at your choosing, but you can't find the electronics.

Thank you so much Dr. Novak 🥰

Thank u for being the best at explaining it! I never had success with them yrs ago but I know know I should have just layed them on the substrate. You’re correct they are hard to find and quite expensive for us budget folks. 🙂. I probably killed them myself by burying them a forth of an inch as I was told. 🙄. They are beautiful plants so I’m goina search for reasonable priced ones and try again. As for the CO2. I don’t have gas but I add liquid CO2. Do u think that would work? Again, thank u for the info and have a great day. Bless, Mary.

ahhh… could it be alkaline water? From my experience algae prefers soft water (especially the green stringy filamentous algae). You mentioned in a video a while back about ‘biogenic decalcification’ which is interesting to me as I do not use CO2 injection to grow plants. Walstad talks about ‘hard water plants’ accessing bicarbonates in the hard water. My guess is these plants are hardwater plants. Valisneria definitely is. That is maybe its advantage over algae in this tank? I avoid soft water. Prefer moderately hard.

yep I agree. Should be an algae explosion. Fish food galore, fish galore, sunlight, soil, 15 hours of light…. total mystery to me

spot on Dr , balance is key brilliantly explained 👌.

Great video sir I think you have done a great thing when you advocated that one should use only iron and potassium gluconate for plant tank. That was the great education where all the other sailors are still selling NPK fertilisers. Those are good for terrestrial plants and not aquatic plants. Change my life. Thank you so much.

Thankq so much Dr. Novak. Greetings from Malaysia. I setup 4 of my tanks with plenum that u taught. All doing well and guppies live longer than usual, compare to previous deep substrate tank. Shrimp breeding is fast and non stop in plenum tank... Half year passed, no water changing just top up regularly, everything fine now. But one thing I found, I was using zeolite for BCB basket in beginning (can't find non clumping kitty litter in malaysia) but failed, it seems suck up the calcium or other thing that makes all plants turned malnutrition looks and cherry shrimp can't molt properly. Until I took it away n add more calcium magnesium.... Thanks for the teaching!!

That's I use floating plants

Is an exception to adding iron to a tank the iron that is used to create an anoxic substrate?

Great points, thank you.

Ive been following you now 4 awhile, in fact, ive set up several tanks using the methods that you speak on. This 1 has me confused, instead of using hydrogen peroxide to control algae why don't you just cut back feeding and lighting...why are you feeding so much? Is it a experiment that you are conducting or something?

Plants need GH. Plants utilize the ions. More than nitrogen or iron imo. Most hobbyist planted tanks do not need or have used Co2, but certainly can help. I can see doing a full dose of iron in a lightly planted tank, with slow growing plants causing a issue. Thanks for sharing.

I'm confused by the juwel led replacement light bar they do and the superfish replacement T8 led lights 😞

Hi dr Novak do you have a email address I would like to send you some pictures of my 55g with the plenum build I tried one email address and it was bounced back ✌️🇨🇦 If not no problem 🙏✌️

I don’t put any fertilizer for long time ago , only I use co2 litter for the same problem , algae always come when I adding fertilizers

Wen you add process to kill aga do you put it in the tank or do you take the plants 🪴 out so can you help me with this

is natural clay is similar to bentonite ? kitty litter with natural clay like that is impossible to get in my country

I don't know if you agree with this but I have heard that the comet goldfish are closer to the wild type of the species and that fantails are basically a comet goldfish with longer fins and are still quite hardy. Also I have read quite often in the literature of the fishkeeping hobby that goldfish will not breed in our temperate climate. I know this to not be true. About 20 years ago I went with a friend to purchase some comet goldfish for her backyard pond that had no fish in it. we got the very cheap fish that I believe are sold for feeders. Over the years the original 10 or so fish have increased to about 100 and in late summer is when I start to see the current season's new fish appear at about the size of a quarter. Also...about my friends pond...when they moved into the house the pond was probably overstocked with a dozen or so large Koi. We cared for them as well as we were able and they seemed to do ok. A few years later at the end of winter, when we were cleaning up the pond we find NO KOI! We ultimately assumed that raccoons from nearby woods had hunted them out and dragged them off to the woods because there was no trace of them in or around the pond.

I have a dirt-planted tank & have really good luck with guppies (oak leaves to treat hard water). I did have to fight a month-long nitrate/ite spike which I found out that the cories dug down into the substrate level. Capping it with sand evened things out & I haven't had a problem since. I feed 2x/day for the babies + cories, but I've also got some shrimp & an algae eater in there to help manage the extra, otherwise they get fed once every 2 days if there's only adults. I have a mix of guppies & regularly cull the older once so they don't inbreed badly. My black moscows, the redtail, platinum, dumbos & a couple wild ones are the hardiest & most vigorous, but I haven't lost a single one over 5 months, apart from culling.

Amen brother 👍

Hello, will these lights promote max photosynthesis like your radion?

Hi, We saw your videos on the Solivita Community and was wondering if you will be recording more. They are really helpful and we plan to visit in the near future. We are looking for more information on activities and lifestyle as we are considering moving there. Thank you.

Hola Doctor Novak, reciba un cordial saludo, he estado viendo algunos de sus videos y debo agradecer por ellos, yo tengo muchos problemas de fosfatos y por ende algas, así que llevo tres semanas que implemente una bolsa con los ingredientes mencionados yo introduje esa arena y piedra roja que en México se llama tezontle bueno espero que sea la misma que usted usa. Y anhelo que estos fosfatos bajen muchísimo. Nuevamente muchas gracias y saludos

Hi, Previously you had done videos on Solivita. They were very helpful! We plan to be there in November to tour the community. Will you be putting out any more videos in regards to community activities and the lifestyle? Thanks!

Love my 20 black mollies. Such beautiful and shiny fish!

Been watching your videos,very informative. Been watching a number of channels including Father Fish and the Walstad method. I used under gravel filters for years in the 70’s and early 80’s. I see that I was doing it wrong. I used power heads! Been contemplating a combo. Undergravel filter with rings underneath and window screen cover then Father Fish method with a short stub to keep a very slow water flow. Thanks in advance.

any sample you make anoxic in internal filter? or is it not possible???

You are one of the best about algae off aquarium moss. Thanks so much

Helli from Oz 🇦🇺 Is it possible to add a layer of aquasoil over the gravel, or is this not suitable for a planted tank? I love your antique aquarium. Great video.

Gravel vacuuming a planted aquarium sounds crazy.

Thanks for sharing. Excellent advise.👍

Thank you, Dr. For another informative video. I want to ask one question whether ozone can be used for freshwater planted aquarium with the plenum. Thank you.
